Fresnel diffraction and the fractional-order Fourier transform
Fresnel diffraction and the fractional-order Fourier transform is a scholarly work, published in 1994 in ''Optics Letters''. The main subjects of the publication include Fresnel integral, physics, fractional Fourier transform, Fourier analysis, mathematical analysis, Fourier transform, ptychography, optics, noise reduction, Fresnel number, Huygens–Fresnel principle, diffraction, Fresnel diffraction, mathematics, Fourier optics, and Kirchhoff's diffraction formula. Fractional-order Fourier transforms are adapted to the mathematical expression of Fresnel diffraction, just as the standard Fourier transform is adapted to Fraunhofer diffraction.
